ATTAGHIN'G MEANS FOR ARTIFICIAL TEETH.

Application filed August as, 1920.

T 0 all whom it may concern.

Be it known that I, JOSEPH B. Fosrnn, a citizen of the United States,residing at hoanoke, in the county of Roanoke and State of Virginia,have invented new and useful Improvements in Attaching Means forArtificial Teeth of which the following is a specification.

This invention relates to improvements in means for attaching artificialteeth to natural teeth, and the principal object is to provide improvedmeans for securing a bridge comprising one or more artificial teeth tothe adjacent natural teeth.

Another object is to provide such means in which it shall not benecessary to crown the teeth neat to the artificial tooth, thus malt inga much better appearing piece of work.

With these and incidental objects in view the invention consists ofcertain novel construction and combination and arrangements of parts,the essential features of which are hereinafter fully set forth andclaimed and several forms of which are shown in the accompanyingdrawings comprising one sheet in which Figure l is a view partly insection of one manner of carrying my invention into effect when a singletooth is to be inserted.

Fig. 2 a view similar to Fig. l but illustrating the application of theinvention to a bridge comprising a plurality of teeth.

Like characters of reference refer to like parts in all views.

This invention contemplates the cheapening of the process of inserting'dental bridges; and the provision of a more sightly appearance in such adevice. in the present practice, the natural teeth adjacent to thebridge are crowned and to these crowns is attached or anchored thebridge. It is the purpose of the present invention to secure the bridgeto the natural teet-hby anchor-pins without the necessity of crowning,thus avoiding a costly process and unsightly result.

Referring more particularly to the draw- Specification of LettersPatent.

ing 1 represents the natural teeth and 2 represents the artificial toothor teeth.

In Fig. l, the artificial tooth is provided with anchor pins 6, thewings 7 of which are expanded into apertures drilled in the the adjacentteeth and are then cemented in place.

in Fig. 2, is shown the same construction as in l but the bridgecomprises a plural ty of teeth.

While I llf' 'e described what are deemed to be the most desirable formsof my invention. it is obvious that the details may be varied without inany way departing from the spirit of the invention and I therefore donot limit myseli to the exact details of construction herein set forthnor to anything less than the whole of my invention limited only by theappended claims.

What I claim asnew is l. A device 01" the class describedcompris a an atificial tooth portion and anchorme is secured in said artificial toothportion side thereof at an acute angle to the vertical axis of saidtooth portion, as and for the purpose set forth.

2. device of the class described compris ng an artificial tooth portionand a wire hmsng one end cement d into said artificial tooth portion andits opposite end extended through the side of the tooth portion at anangle to the "w portion for seating i tooth.

as and tort-he purpose set forth.

device of theclass described coinan 'iieial tooth ptrtion and a wire h..ing one end bent in tidformation and seemed in said artificialtooth andhaving its other end extended through and beyond the lateral edge of theartificial tooth for anchoring the same to a natural tooth.

In testimony whereof I have allixed my signature.
